Remove specific text in output line

Anyone knows how to remove specific text in a output in line?

grep -v is the normal way in my world. some context would be nice though. probably best to suggest you just read through the grep manpage...

tried with "grep -v", it helps to grep lines which is exclude the text we filter

I am looking for a way to remove the text in a line.
Example: This is a testing line
I would like to make the final line with the word "This is a test line"

Can I know how can we do this?

In that case you might want to try "sed"

Code:

sed -i -e 's/testing/test/'  /path/to/file

might get you started.
Lots of good tutorials around.

Please find the below scenario

Steps
------
1) search a file call abc.txt
command: find / -name abc.txt
example output: /tmp/testfile/abc.txt

2) Obtain the directory for the file location
command: ???
example output: /tmp/testfile/

Since the file location for abc.txt could be dynamic. Can I know is there anyway to find a file and then we obtain the path of the file?

Really appreciate if someone can help on this.

well we're not here to do your homework for you, which this really looks like. you need to study yourself... i'll tell you that there is a dedicated standard bash command to do exactly that though.

I had tested with grep, awk and sed which also didnt work for my case.
If there is a standard bash command to do it, would you mind to share with me?

As acid_kewpie said, you need to do your own homework. But here's a hint:
man bash, lookup the section 'Parameter Expansion'

well yes, that's certainly one way, not the way i was thinking off at all though. so many ways... so little probelms
